The idea that netmasks must break on octet boundaries is ancient history. See Section 5 of RFC1338 at, for example, http://RFC.net/rfc1338.html. > A netmask should always be x number of one bits, followed by all zeros, hence > the /x shorthand. > > as an example, 255.255.255.16 would not be a valid netmask, but > 255.255.255.192 would. The "validity" of the netmask depends on convention, but it is true that it is highly unlikely to be useful to create discontiguous netmasks.
